After installing Microsoft Update KB3133977 for Windows 7, some users may encounter a “Secure Boot Violation” , which makes the system fail to boot into the operating system.

To protect user’s systems from malware attacks, ASUS motherboards implement the Microsoft Secure Boot feature by default. This feature performs a legal loader check to boot into the OS. As Windows 7 does not support Secure Boot (https://technet.microsoft.com/en-us/library/hh824987.aspx), with the update of KB3133977, the system might detect inconsistent OS loader keys, resulting in boot failure.
